UNITED STATES PATENT OFFICE.

A. B. NIMBS, OF BUFFALO, NEW YORK, ASSIGNOR vTO HIMSELF AND J. C. CLIFFORD, OF SAME PLACE.

IMPROVEMENT IN THE MANUFACTURE OF ELEVATOFt-BUCKETS.

Specification forming part of Letters Patent No. 42,734, dated May 10, 1864.

To all whom, it may concern.-

B'e it known that I, A. B. NIMES, ofthe city of Buffalo, county of Erie, and State of New York, assignor to A. B. NIMES and J. C. CLIF- FORD, have invented certain new and Improved Elevator-Buck ets and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to to the accompanying drawings and the letters of reference marked thereon, in which- Figure I is a vertical cross-section of my im )roved bucket 5 Fig. II, a front elevation ot the same. Fig. III is a detail section showing the manner of fastening the front to the ends of the bucket, and Fig. 1V represents the bucket spread out or developed upon a plane surface. l This invention consists informing an elevator-bucket with the band around its upper edge of one sheet or piece of metal, which is cheap, strong, and durable.

Letters of like name and kind refer to like parts in each ot' the figures.

A represents the back or vertical side through the holes a', in which the bolts which secure the bucket to the elevating-belt pass.

B represents the curved front or dipping side ofthe bucket.

C represents the ends of the bucket, to which the curved front is fastened by a double lock-joint, c. (Shown in section in Fig. III.)

D represents a broad band or belt passing around the upper edge of the bucket and giving strength and 4stiituess to the same.

By a reference to the developed plan, Iig. IV, and the bllowing description the formation of the bucket, with the stiti'ening-band, will be readily understood. The end pieces, C,

are turned upon the line c2 as an axis until their surface is at right angles t the surface ofthe back A. The front B is then turned upon the line b as an axis (at the same time being` given its proper conveXity) until it meets the end pieces, C, to which it is secured by the double loekjoint c', (shown in Fig. 111,) the leaves c3 and b3 givin g the necessary metal for the formation ot' the joint. The band D on the end pieces is then turned down upon the line c5 for an axis until they lneetthc end pieces, its edge being turned again on the line c6. The band D on the back A is turned down on the line t2 for an axis, and is turned or doubled under on the line a3. The earlaps a4 lap around onto the end pieces, O, and are secured by the rivets a5. The band D on the front is turned down on the line b2 and turned or doubled under on the line b. The earlaps b4 lap around onto the end pieces, C, as seen in Figs. I and II, and are secured by the rivets b5.

E represents a brace running through the center of the bucket, and riveted to the front and back, as shown at e e2. There heirg no joints in this bucket which require soldering, it may be made of sheet-iron, which material makes a much stronger, cheaper, and more durable bucket than the tin ones now in use.

I claim- An elevator-bucket, with its strengtheningband, constructed and formed from one sheet or piece of metal, substantially as herein described.

A. B. NIMBS.
